Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a type of connector,
The present invention relates to a connector having a particularly simple structure and a good electric shielding function.

[0002]

2. Description of the Related Art With the rapid development of electronic devices and computer technology, connections between electronic devices and their peripheral devices have become more frequent, and electromagnetic interference from the outside world has been increasing. As a result, the industry will typically utilize a type of connector that collectively and accurately transmits electronic signals having high speeds and frequencies.

In a conventional connector, as shown in FIG. 1, a shield plate 4 and a terminal 3 are installed on the seed connector 2. The shield plate 4 is provided with a long hook 5, and by contacting the long hook 5 of the shield plate 4 and the terminal 3, a signal can be transmitted and at the same time electromagnetic interference from the outside can be prevented.

[0004]

However, this type of connector realizes the shielding function by contacting the long hooks 5 of the shielding plate with the terminals. In this type of contacting method, the tightness of the connector is clearly shown. In addition to being insufficient, the long hook of the shielding plate is extremely likely to break the contact between the long hook and the signal terminal when it is deformed under the influence of high-strength external force. It cannot achieve the effect. Further, this type of connector can achieve the shielding function by adding one shielding plate, but its structure is too complicated and the cost is increased. Therefore, how to provide a connector having a simple structure and a good electric shielding effect is a problem to be solved by a trader.

An object of the present invention is to provide a connector having a simple structure and an excellent electric shielding function.

[0006]

In view of the above object, a connector according to the present invention has an insulating main body and both shield devices inserted into the insulating main body. A groove is provided in the center of the insulating body, a plurality of insertion grooves are provided on both sides of the groove, and a plurality of pinholes are provided corresponding to the bottom surface of the insulating body and the locking groove. Shielding pieces are installed in the central portions of both of the shielding devices, and are respectively inserted on both sides of the insulating main body, and one side edge portion of each shielding piece is further stretched and bent to be arranged in parallel in a plurality of rows. Formed terminals. The terminals are positioned and fixed to the insulating body by inserting the plurality of insertion grooves and the plurality of pinholes correspondingly on the insulating body in this order. The other side edge of each shield can be further extended and bent to form a plurality of parallel spaced apart tails that can be welded to the circuit board.

[0007]

EXAMPLES Please refer to FIG. 2 to FIG. The connector 1 of the present invention has an insulating main body 10 and both shield devices 20 inserted into the insulating main body 10.

The insulating body 10 is a vertically long housing, and a groove 11 is provided at the center thereof, and a plurality of insertion grooves 12 are provided on both sides of the groove 11, so that the insulating body 1
The bottom surface of 0 is provided with a plurality of pinholes 13 corresponding to the insertion grooves 12, respectively, and a plurality of locking block pairs 14 are installed on both sides of the insulating main body 10 between the locking block pairs 14. The engaging groove 15 is formed in each of the.

A shielding piece 21 is installed in each of the central portions of both of the shielding devices 20, and the shielding pieces 20 are inserted into both sides of the insulating body 10, and one side edge of each shielding piece 21 is further A plurality of terminals 22 are formed that are extended and bent, and are arranged in parallel and separated from each other, and the terminals 22 are respectively inserted into the plurality of insertion grooves 12 and the plurality of pinholes 13 in the insulating body in this order. By indenting, the insulating body 10 is localized and tightened. A plurality of tail portions bent to the other side edge portion of each shield piece 21 and locking arms 24 corresponding to the locking grooves 15 of the insulating body 10 are extended, and the tail portions 23 are welded to a circuit board. Will be done.

When the device is attached, first the shielding device 2
0 terminals 22 on the corresponding insertion groove 1 of the insulating body 20
2, and the terminal 22 and the insertion groove 12 interfere with each other. Further, the terminals 22 are pressed downward to be localized in the corresponding pinholes 13, and at the same time, the locking arms 24 are also inserted and fixed in the corresponding locking grooves 15. Then, these tail portions 23 are attached to the circuit board by welding.

By utilizing the above connector, the shielding device can not only realize the electromagnetic interference shielding function, but also the terminal and the shielding piece are integrally molded to improve the contactability of the connector. The structure is simple and an excellent electric shielding function can be obtained.

[0012] In general, the present invention has sufficient requirements for patent registration, and therefore, patents should be registered by law. Further, the above is merely specific examples made according to the present invention, and does not limit the scope of the claims of the present invention. Modifications or changes in details that can be made based on the present invention are all claimed in the scope of the present invention. Shall belong to.
